Context

This was an RSU vesting event with a net share settlement: issued shares were used partly to satisfy withholding and the remainder sold in the open market. That pattern is a routine liquidity/tax event rather than an outright purchase by the insider. The reporting person is an officer (CLO), not a 10% owner.
